Structural-phase state and tribological properties of the foamed self-fluxable alloy PG-10N-01 modified by the borated material

Abstract

Problem. The paper presents the results of a study of the microstructure, phase composition and wear resistance of deposited coatings based on the PG-10N-01 alloy modified with the developed composite material containing titanium diboride, nickel boride, titanium oxide and iron. Goal. The aim of this work is to develop a composite material (CM) based on the powder material of the Ni-Cr-B-Si system, modified by a composite material (microns) obtained using a SHS process containing titanium borides and other elements for hardening machine parts subjected to abrasive wear. Methodology. To achieve this goal, it is necessary to develop a technology for obtaining microns and conduct studies of the structure, phase composition and abrasive wear resistance of deposited coatings from CM based on the Ni-Cr-B-Si system material modified by a composite material with elements containing boron. Results. The functional features of multi-functional road panels of pavement are revealed and their scheme on the roadway is presented. The principle of operation of the road as a unified system of multifunctional road surface panels has been researched. The scheme of implementation of road marking and automatic control of road traffic is presented. Originality. To increase the abrasive wear resistance of the deposited coatings based on the self-fluxing alloy PG-10N-01, it is proposed to use a modifying composite material containing titanium and chromium borides obtained using the SHS process. Practical value. To increase the abrasive resistance of machine parts, a charge composition has been developed to obtain a composite wear-resistant material using the SHS process. This composite material when modifying the surfaced coating with PG-10N-01 alloy increases its abrasive resistance by 1.7 times.
